|Repairing Nothbridge Fan|
On my IC7-MAX3 motherboard during the
installation of my Zalman CPNS7000 cooler the stock Abit Northbridge fan
started to play up. You all know the noise... buzzing, vibrating and
generally being a pain in the ass!
I spent £125 on buying this (at the time) top of the line board and i don't want to find a basic cheap Chinese sleeve bearing fan on it. Come on Abit you should spec something decent cooler here, at least have a ball-bearing fan!
Ok, what causes the noise?
Why should i bother fixing a fan like this?
Ok, so how do i fix it?
Get the fan off the heat sink and remove the sticker off the back, this will reveal the shaft and a small plastic c-clip
Remove the c-clip with some small watchmakers screwdrivers, sewing pins can also work very well.
Once the fan blade assembly is off remove the small rubber/plastic washers from the spindle and remove all the old grease from both the washers, spindle and the bushing
Then simply apply some very light silicone lubricant to the washers and spindle and put it all back together the way it came apart. Then reinstall back into your PC!
